HYDROCARBON-BURNER.

SPECIFICATION forming part of Letters Patent No. 712,142, dated October 28, 1902 Application filed November l1, 1901. Serial No. 81,934. (No model.)

'l'o a/ZZ whom/.it may concern.:

Be it known that we, CHARLES R. KITTLE and GEORGE E. HARPHAM, citizens of the United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

Our invention relates to that class of hydrocarbon-burners in which crude petroleum and steam are used as a fuel and are not commingled in the burner; and the objects thereof are to provide a burner of great efficiency, simple in cons truction, which can be cleaned without removing the burner from Ythe firebox.

Heretofore in the use of all hydrocarbonburners with which we are acquainted in which crude petroleum and steam are used as a fuel and are not commingled in the burner trouble is encountered sometimes in the oil-ports becoming stopped up or scale or other substance lodging in the steam-port, thereby producing an uneven fire and rendering it necessary to cleanse the burner. Owing to the construction of these burners it is necessary in most cases to remove the burner from the fire-box, as the ports are rigid-that is, cannot be expanded or contracted to clean the ports.

In our improved burner the oil-chamber and steam-port can be enlarged beyond the size thereof when used for steam production and the chamber and port cleaned in a few seconds Without removing the burner from the furnace.

In the drawings, Figure l is a side view of our burner partly broken away and a view of a portion of a fire-box. Fig. 2 is a front View of the burner-tip. Fig. 3 is a central longitudinal vertical section of the burner -tip. Figs. 4 and 5 are plan views of the oil-chamber and steam-chamber, taken on theline X X of Fig. l looking in opposite directions. Fig. 6 is a rear elevation of thesteam-regulating valve and a portion of themechanism by which it is operated. Fig. 7 is a plan of the oil-chamber with its top removed.

The burner-tip is composed of an oil and a steam chamber. The oil-chamber is disposed over and projects beyond the steam-chamber, with outlets of the oil-ports terminating in the plane which forms the top of the steamchamber, so as to deliver the oil into the path of the steam as it issues from the steamchamber at right angles to its course. As the atoms of oil lpass out of the oil-ports the atoms of steam cut them off from the atoms of oil above and still in the oil-ports, thereby more completely atomizing the oil than is possible when the oil-ports discharge the oilalittle above the course of the steam-jet. We have found by experiment that if the outlets of ,the oil-ports are elevatedabove the line of the course of the steam as much as one-sixteenth part of an inch the oil is not as perfectly atomized as when the outlets are in the same plane as the top of the steam-jet. The one-sixteenth of an inch or any distance whatever of elevation of thel outlets of the oil-ports above the top line of the course of the steam-jet permits the atoms of oil to bend in their course and to ride on the top of the steam instead of being cut up into atoms and being carried out into the furnace in the steam, as is the case in the use of our burner. As these ports are slightly in front of the steam-port, the action of the steam thereon prevents the formation in and around the ports of carbon, thereby preventing their stopping'up from this cause.

In the rear end of the casing A of the oilchamber is screwed the oil-pipe B, which ex- -tends to and is screwed into the fitting C. In

the casing of the oil-chamber is au enlarged upper portion a, which will be denominated the distributing-chamber, in communication with the bottom of which is a circular supply-Well b, which is alsoin communication With the oil-pipe through port c and is preferably centrally disposed in the bottom of the distributing-chamber. In communication with the bottom of the front portion of the distributing-chamber is the port-well d, the bottom of which is closed by the removable port-plate e, in which are one or more Vertical ports f, which discharge' the oil into the path of the steam at right angles toits course. The port-plate is preferably made of steel, because the principal wear is on that portion thereof surrounding the ports, and by making it removable when it becomes worn the plate may be replaced, when the burner- IOO tip is as good as new, and by removing the plate and putting in another with a greater or less number of ports therein the burner without change is adapted for greater or less steam production, thereby enabling us to use the same burner, with the exception of the port-plate, in a large or a small furnace. We have shown the port-plate with a plurality of ports, as we deem that construction best, because it breaks up the oil into a plurality of small streams; but, if desired, a single narrow port of the desired capacity might be constructed in the port-plate.

By separating the supply-well from the portwell the oil rises into the distributing-chamber and flows thence evenly into the portwell, thus giving to each port the same quantity of oil, and thereby preserving an even flame. The front portion A of the casing, which is in front ofthe ports in the port-plate, is detached from the other portionv and is held in place by rod D, which is affixed thereto and runs through the oil-pipe B, fitting C, and through stufng-box E, and wheel F is screwed thereon and is held against being screwed oif by nut G, which also limits the longitudinal movement of the rod and the detached front of the casing when the oil-chamber and oil-ports are being cleaned by the steam in the usual well-known manner, as the steam will cause the detached portion of the casing to separate from the other portion as far as the wheel F is screwed back from the stuffing-box, and any chips or other substance that are too large to be forced through the ports may be blown out around the detached front.

The steam-cham ber is removably attached to the bottom of the oil-chamber by bolt H, which passes through the port plate and screws into the casing of the oil-chamber. In the rear end of casing I of the steam-chamber 7L and in communication therewith through port QI is screwed the steam-pipe J, which runs to and is screwed into fitting K. In the steamchamber and having a vertical movement therein is steam-valve L, having a reduced upper front lip L', by means of which the steam is regulated at the outlet or steam port M, the front portion of the casing of the steamchamber being cut away to form said port. This lip is a little wider than the steam-port and has a smooth top, so that when the valve is moved to its extreme upper point the lip will contact with the bottom of the oil-chamber and completely close the steam port. The steam-valve moves on bolt H and is guided thereby, aswell as by the casing of the chamber.

In the lower portion of the steam-valve is recess N, in which works eccentric O on the steam-valve-operating rod P to give the valve its vertical motion. This rod extends through the casing, steam-pipe, iitting K, and stuing-box Rin the fitting and is provided with a handle S, by means of which it is rotated to produce the vertical movement of the steamvalve. This rod has no longitudinal movement. Fitting K is connected with the steamsupply (not shown) through pipe T and connections, and fitting C is connected with the oil-supply (not shown) through pipe U.

V is the usual valve-controlled steam bypass for use in cleaning out the oil-chamber with steam. The by-pass and regulating devices are placed exterior the back wall X of the furnace, while the tip projects into the furnace, as shown in Fig. l.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. A hydrocarbon-burner, comprising an oil-chamber having a vertical discharge-port and a detachable front, and means to move said detached front away from the other portion, when desired; and a steam-chamber having a horizontal discharge-port disposed below said oil-chamber.

2. In a hydrocarbon-burner, composed of an oil-chamber disposed abovca steam-chamber, a removable port-plate affixed to the bottom of the oil-chamber having one or more Vertical openings therein, which terminate in the plane of the top of the steam-chamber and are adapted to discharge the oil in the path of the steam, at right angles to the course of the steam.

3. In a hydrocarbon-buruer, an oil-chamber disposed above and projecting beyond the steam-chamber, composed of a well in communication with an oil-supply pipe, said well opening into the bottom of a distributing-chamber; a distributing-chamber having the front portion thereof in communication with a port-well; said port-well having one or more vertical ports in the bottom thereof, opening in front of the steam-port in combination with a steam-chamber, having a horizontal discharge-port opening in the rear of and immediately below the oil-port, and a vertically-movin g steam-valve having an upwardly projecting lip with a smooth top adapted, on its eXtreme upward movement, to close the steam-port, and means to operate said valve.

In witness that we claim the foregoing we have hereunto subscribed our names this 5th day of November, 1901.
